The simple answer is no. You could set up two tactics with the "roaming winger" on the right wing in one of the tactics and on the left in the other tactic and switch between them every so often.
Go into your winger's player settings, and use the 'swap positions' thing to select the other winger. (So if you go into the LW's settings, you would pick to swap position with your RW)
